Scientists have now identified some exoplanets that might have suitable temperatures for liquid water and enough UV light for the chemistry thought to have led to life on Earth.
Do sharks have bullet-like strikes? Do they have super-vision? Can they take down prey in milliseconds? Mantis shrimps have these abilities - and more - to put them among Earth’s most impressive predators.
By tomorrow morning, if your sky is dark, you'll see that the moon has moved in its orbit around Earth. It will have passed Aldebaran and be moving along the "horns" of the Bull.
Have fun watching the moon in the morning sky this week. And know that the stars it's passing are the same ones we'll see in the evening 6 months from now.
Those beams of light shooting out from the horizon or down from the clouds are called crepuscular rays, or sunrays. Beautiful, mysterious and very noticeable. Photo by Nicholas Holshouser. More great pics here.
